Yes, you erred.
It’s much simpler than you make it:
38 Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.
How can a newly baptized baby have any sins to be forgiven?
What does the baby receive when s/he receives the gift of the Holy Spirit?
Catholics USED to say Holy GHOST but that disappeared over the decades. The Protestants have obviously FOLLOWED the Catholic change.
How was defrocked ROMAN CATHOLIC PRIEST, Father Martin Luther, allowed to disregard the Apostolic Tradition and all the teachings of the Catholic Church that had ALREADY been in existence for ONE THOUSAND FIVE HUNDRED YEARS?
Now there are over 30,000 DIFFERENT Protestant denominations?
Is THAT keeping it simple?
This ALL started with defrocked Father Martin Luther. I hope he's happy with that.
